IMPROVEMENT IN CORN-PLANTRS.

The Schedulveureferred to in'these Letters Patent and making part of the same,

Be it known that I, HENRY AUSTIN N1crroLLs,.in the city and 'county of USt., Louis and State' of Mis-v souri, have invented new and useful Improvements in Machines for Planting; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation of the said machine, reference being had to the annexed drawing making a part of this specification.

Description of Amwxd Drrriviilg. Figure 'l is au isometrical perspectiye view of the machine, showing the whole of ymy invention, except *uneven surfaces. The' whole or any portion of this machine may be constructed of wood, iron,'or any other material adapted for that purpose, and most readily -obtained in the place where the machine may be manufactured.

A A's the cylinder, which works inside the drums D D, and car'ries'the seed-corn from the: hoppers to the leaders E.

'B B is the shaft connecting the cylinders A A, and, by a crank-connection with' the counter-wheel H, it regulates the action of, and communicates motion to, the cylinders A Af" 'O C C are studs placed insidey the cylinders A A, and made fast by a screw. 'lhey are a portion of the' contrivance used for regulating the dropping of the gram.

' D D are the drums covering the cylinders A A and appurtenances.

E .is one of the' `leaders, receiving Jhe seed-grain from the receptacles in the cylinders A A and depositing it in a furrow inthe soil,l and immediately back of the-plows.

.F F are hoppcrs, in which is to be placed the' grain that it is intended to plant. y 1

G is a large center-wheel, withv cogs. It is` connected, by a shaft through its center, with the carriage-wheels, from which it derives motion, and, by connecting its cogs with vthose of the cogs and shai'tv marked M M, it communicates motion to the entire working-parts ofthe machine. This wheel Gand its counterlwheel H may be oflarger or smaller dimensions, to suit purchasers, and to increase or diminish the number of droppings'made by the machine.

His a counter-wheel, with cogs, connected, bythe cows and shaft M M.l with the center-wheel G, andcommunicating motion, by means'of a crank, to the cylinder-shaft B B.

I is "a forward carriage-wheehand isp'adapted' to this machine for the purposes of keeping the weight of the machine and itsl contents from off the horses backs, tofacilitatein turning'in short spaces, and for greater convenience in preserving a steady contact of the planting contriv'ances with the soil in which the y grain is tobe planted.

Two `plo ws are'.` attached to the frame of the machine, beneathanda little forward of the drums D D, byheavy bolt-hinges or joints, and sustained in posi tion, when in' operation, by stout chains. When not in use, these plo'ws ,may be raised, by virtue of the bolt-hinges, to a parallel position beneath and for` ward of the frame ofthe machine.

* Theplows are composed of two equal-sized shears eachhan'd are used for theA purpose of throwing up a smooth, dat-bottomed, or square furrow, inwhich the seed-may have-sufficient room to scatter when dropped into it through the leaders E E, which are situated immediately back of the plows. i

The depth of thefurrow maybe regulated by rais.

ing or lowering thel plowshares,-by means of a small bolt attached-tothe chain fastened on the frame; of f the machine. l

K K are the coverers, located beneath the frame, inside and forward of the back carriage-wheels. The

coverers are composed of two separate plates, connected by aforkecllever attached to the frame ofthe machine, and held in position by strong boit-hinges and'chains, and are subject .to the same movements, to stop their working, as the plows. The outside or t forward plate-throwsthe soil from within and beneath the carriage-wheels into the furrows previously dug by the plows. The inside or rear plate of the coverer takes such soil as may have been left by the forward plates, 'throws it into the furrows, and thereby com pletes the covering of the furrows and the planting of the grain.

M M are cogs at :each end of a lever, connecting the center-wheel G with the counter-wheel H, and are used to communicate movement from one to the other wheel.

L L are two levers att-ached to the frame of the inachine and the shaftand cogsM M. These levers are usedto put'on-or throw oif the connection of the Apogs MM with the co'gs of the wheels G and, H. The forward lever L is used to throw on or o' the c onnection at the counter-whoelH, and sets the machine to-plantf to work or stops the entire working-portion of the machine. By means of tliese levers the machine Vcan be so disconnected that it can be driven over any roads fwrnlplace to place, without interfering in any inanner with its working-parts.

The lever attached tothe cylinder-shaft B B can be -lysed for dropping the grain, at'the will ofv the drivel', when the connection at the counter-wheel H andthe cogs M M is thrown olf, and is more particularly-use fnl in replanting, as one or both the planting port-ions of the machine -rnay beused and regulated by this shaft-lever, as the necessity of the work may require. P P are plugs-used to regulate the size of the seedrec'ep'tacles in the studs G G, as shown in iig. 2.v They increase or diminish the number of grains dropped. These plugs are operated on by the hand, through openings in the cylinders A A, which openingsare shown in the'drawing.

The rightvhand aft carriage-wheel revolves on its axle, for the purpose of facilitating the turninglof the machine when the planting-parts are in operation.

The left-hand aft car1iage-\vheel, being firmly fastened tothe axle, revolves thesame, communicating motion to the center-wheel G, and, through it, to the entire machine when the connections are on.

Claim.

vI claim as my inventionrlhe particular combination of the wheels G and H, the shafts B B and M-M,'drums D D, cylinders A A, studs C C, leaders E E, covers K K, levers L L, and pl'nngers l? 1)together-with the plows, substantially as set forth, and for the purposes herein specified.
